For some reason, I have two DHCP Servers in my trusted zone. One for IP 10.42.1.1 and 192.168.1.1. for the other entry.

Are they REALLY needed if I have a hardware firewall in my DSL router/modem?

How do I trace back to find out what software is using these servers?

Re: DHCP Servers in Zones???

Yes, this is to ensure you are able to obtain an IP (and having your PC factually connected to the Internet) from your router.

You should check which IP has your router (=your DHCP server) to remove one of the two addresses probably related to another or an old connection. The simpler method is to check in the ZA zones which network is listed. Something like 192.168.1.0/255.255... Etc? Then remove the DHCP with 10..... address.

Which software use DHCP? Its your Operating System. The DHCP server is in practice your router and windows needs it to get an IP and connect to internet or share resources with other PCs in your LAN Those IPs are internal and cannot be reached from the outside.

You may not need to have the DHCP IP under the ZA zones set as TRUSTED if you have already the network 192.168.1.0/255.255.... set as TRUSTED (normally the default at install.

To understand better what is dhcp and reserved IPs you may want to review the following:

ipconfig /all : Displays the full TCP/IP configuration for all adapters. Without this parameter, ipconfig displays only the IP address, subnet mask, and default gateway values for each adapter. Adapters can represent physical interfaces, such as installed network adapters, or logical interfaces, such as dial-up connections.
